Hi,

I'm using the sci interface to send datas to my computers on his RS232 entry.

In Fact, tests are done qith the real time emulator MDT2.

So with the hyperterminal of my computer i send 4 bytes to my ST7, and after that my ST7 send to my computers the same 4 bytes.

The problem is that these 4 bytes are not the same and if i send an ascii code to the computers (0x42 for example) the computers do not print 0x42 value.

I don''t know where is the problem. could you help me?

You can debug your application by-

1. Ensure that baud rate is same on both sides.

2. Try to transmit a byte from your side but not the byte received through hyperterminal ( if it is ok it means there is a problem on the reception side).

3. Check the data on both rx & tx pins and compare them.

Hope it helps!
